Bash Script for Brightness Controls For Samsung 535u3c in Lubuntu/Ubuntu/Linux

The default proprietary linux display drivers in Xorg for Lubuntu which I installed in my Samsung 535u3c ultrabook doesn’t work for the lcd brightness settings (xbacklight doesn’t work for this notebook). After setting up my sound successfully, this is the other issue I found for the ultrabook.

In Lubuntu, you can set key bindings by editing the ~/.config/openbox/lubuntu-rc.xml file and by adding keybindings to set your lcd brightness; this is an example below (add or edit this on the said file to your liking – like setting other keys instead of the below to do it – you cannot do this with the default fn+F2/F3 key combination because these are hardware keys):

So far, I’m satisfied with this laptop/ultrabook. Does all my needs and development with it (it replaced my badly overused old netbook) – battery life is average though, but I plug it most of the time anyways. I haven’t tried gaming as this is basically my mobile work machine, but apparently it does very casual gaming just fine based on benchmarks I’ve tried.

For general use, the default radeon open source video driver may do just fine in Ubuntu. You may just need to adjust your sound configuration if you can’t hear anything from the speakers (see my other post on audio).
